I thoroughly enjoyed flying a loaned Ace 160 on several occasions & I reckon it facilitated faster climbing & easier handling than my similarly generous Solarwings Rumour 14.5m.
As I observed on more than one occasion, potentially there is a drawback to flying any glider that facilitates exceptionally easy handling enabling the pilot to really slow it down in order to take maximum advantage of the available potential climb rate & that drawback is that when you eventually inadvertently stall a wing typically as you move into a volume of the airmass where there has developed an overwise insignificant airflow sheer condition, if the glider does stall often the consequential spacial reorientation will be more severe requiring extra time & altitude in which to recover than a pilot who has become familiar with flying a succession of less obliging gliders would otherwise anticipate.
